DISPLAY COUNTER.

application mea april 11', 1927. serial No. 182,738.

My invention relates to a 'refrigerated service display counter for perishable articles of food such as meat and thelike; the invention having for its object the provision of a construction whereby increased etlici-ency and economical refrigeration are obtained while at the Sametime a more sanitary display case or counter is provided whereby the food stuffs or meats are maintained at the proper temperature or in the desired chilled condition. Furthermore, with my improved construction the chilled condition in the food-stuff or meat holding portion, namely the bottom of the counter will be retained for a considerable period of time after the refrigerating unit has been shut down. A

The above enumerated objects and advantages, as well as other advantages inherent in my invention, will all be readily comprehended from the detailed description of the accompanying drawings, wherein. I

'Figure 4 is a detail sectional' view taken on the line 4.--4 of Figure 2 looking in the direction of the arrows. Figure 5 is a transverse sectional view Aof a portion of a display counter showing a modified form. v v

My invention relates to a refrigerated service display counter more especially intendedl for containing and displaying meats and other food stuffs requiring a low temperature while on display. The specific type of display counter embodying my invention illustrated in the drawings involves a suitable supporting frame or lower portion 10, while'the upper portion constitutes the display counter proper. The forward side of the display counter usually consists 0f glass as at 11, held in place by suitable frames and at bottom by a sheet metal sealing strip 12, see Figure 2; while the rear or salesmans side involves suitable slide doors as 'at 13; the front and rear sides being preferably arranged at suitable and different inclinations so as to permit proper visibility of the contents of the counter. lThe rear or salesman-side of the counter, at a suitable intermediate point, is provided'with an inset ledge or scale holding portion as at 14.

Display counters of this generall character are usually provided along thebottom and within the display portion withrefrigerating coils as at 15 arranged in a horizontal plane lengthwisefrom end to end intermediate of the front and rear sides of the display counter, as more clearly shown in Figure 3, having the ingoing pipe 16 andthe outlet pipe 17 which lead to a mechanical refri erating unit located at a suit-able place. y improved display counter also involves the chilling coils 18 connected with the horizontall'ydis osed pi e 19, a section whereof is connecte with t e inlet pipel16. The coils are arranged in well known manner to induce proper circulation; the exposed portions of the coils inducing or exciting air circulation in the counter.

The chillingcoils 15 have heretofore beenr arrangedlalong the bottom of the counter with the bottom .of the counter usually provided with a suitable perforated metallic plate arranged above "the coils to provide an inner meat or food-stuff holding bottom.

My invention contemplates providi the bottom of the display counter with a suitable wall of insulation as at 20, any suitable insulating material, such as cork or the like being employed. The c'oolino coils 15 are arranged a suitable distance atbove the main bottom of the display counter in order that' a considerable thickness of insulation may be employed as shown in Figure 2. The insulation 20, which is usually of cork, is formed about the lower sides and ends of the coils'so as to provide a well or depression of depth substantially equal to the diameter of the coils. The depression or channel is then provided with a layer 21, of waterproof and cold resisting material which is poured into the depression so as to fill the channel and practically embed the chilling coils with the .exception of the immediate upper surfaces thereof. The la er 21 is then covered with a layer 22 of ydraulicallyI lor iange portion 23 along the forward side of the case and the upstanding lip or flangev portion 24 along the rear side of the case in order prevent moisture or water, durmg cleaning operation, from 'passing intermediate of the top layer and the frame andthe cork or insulation of the case.

In Figure 5 I show a modification -of the invention. The display counter of Figure.

5 in general construction may be like that previously described, having the main bot-n tom 25 provided with a suitable layer of lnsulatlng material 20 of cork andthe like as, 1n the c'onstruction described; with the cooling coilsf15 in the well or ,depressionA -formed in the upper surface. The coils 15 are preferably entirely embedded, except for the tops thereof, .in a plastic water-proof,

cold resisting material 21. The tops of the coils are then preferably covered with the vlayerof cementitious material 22 like in the previously described construction; and before this layer 22 has become set, I place a w 1ch will readily transfer the cold, such as porcelain enameled iron; the plate being pressed into the cement so as not to leave an air space therebeneath. Itis apparent that a bottom which is impervious to mois ture is thus provided and a sanitary counter produced while. at the same time a -good cold conducting bottom for conveying the chilling effect of the coils to the material placed on the bottom of the counter is obtained.

With these constructions it is apparent that' the coils are fully covered or encased and that with the insulating material 2O therebeneath andthe cold resisting plastic ma* terial around thesides `of the coils,'the pipes or coils 15 are sealed against air, the cold temperature or condition of the coils conserved and the cold practically entirely transmitted to the outer or top covering 22Y of cementitious material, or to the metal plate 26 when the latter is employed.

The plate 26, like the cementitious material or covering 22, is preferably formed along the edges with the upwardly disposed flanges or ralsed portions 27, 28 which may extend slightly beyond the insulation and the coil embedding material to prevent water or moisture finding its way to the insulating material therebeneath. As a result a more sanitary display counter is .provided than has 'heretofore been the case; while at the same time a counter which can be readily cleaned is produced.

The colls as can be seen in the drawings, are encased in a jacket, the lower part This layer is- Iplate of metal 26 thereon, namely a metal wher'eof consists of the insulating material 20 and the water-proof, vcold resisting `material 21, while therupper part consists of the hydraulically setting cementitious mai terial '22 with 'or without the comparatively heavy metal plate 26; vthe upper'part of the j acketv being a ready conductor or transmitter of the cold temperature-'of thecoils, While at the same time retaining its chilled condition vfor a comparatively long period after the refrigeratingunit has been shut,l down. As a result, a considerable saving in operating expense is effected because of the retentive quality of the 4upper covering, while at the same time a more effective and uniform chillin of the meats and other "food-stuffs is o tained because the latter ing from suitable points adjacent to the forward side and opposite ends of the counter; itbeing usual in counters of this character to have the bottom of the counter slope slightly downward toward the front .in order to increase visibility of all the articles on display. The drains 29 may have ingress of air and insects.

It is understood, of course, that counters of the character in question are not intended foruse as refrigerators but merely as displa cases for certain food-stuffs or meats, an therefore it is merely essential to maintain a proper low temperature at the bottom offthe counter where the food-stuffs or meats vare arranged in visible order.

In forming the rear wall of the counter at anA intermediate point with a weighing scale holding chamber 14, op ortunity for arranging the upper coils 18 1s afforded at a place where they will not interfere -with the salesmans vision of the counter contents and his accessibility to the counter. At the same time the scale will be conveniently located adjacent to the slides or doors 13 so that weighing of various cuts of meats or other food-stuffs, beforel final selection, may be made and the unselected material relaced in the count-er, without material loss i 1n its chilled condition.

The invention, as exemplified in the drawings, has been described in terms employed lmerely for description and not as terms of limitation.

What I claim is:

A display counter of the character described having glass side walls, the bottom being provided 'with insulating material formed to rovide a recess on its upper surface exten ing substantially from front to rear and from end to end, refrigerating coils suitable closures or water-seals to preven t s 5' thereof, a covering vo cold conducting and tom of the counter.

arranged in the recess,'an enclosure for said plastic material and the tops of the coils coils consisting of plastic water and cold-reso as to prevent passage 'of au' and moisture sisting material illing said recess and em therebeneath, and drain outlets extending 10 `bedding the coils exce t for the-top surfaces downwardly from said covering-to the bottempe'rature retaining cementitious material V i u Xarranged in intimate Contact with vsaid FRANK W. DAEBHCKE.
